Rack-Cache and Streaming... incompatible?

[Matthew Fordham]

Hi all,

I am attempting to stream a CSV file from a Rails 3.2 application. All works as expected IF I disable Rack-Cache... but I really want to keep the caching if possible. Setting 'Cache-Control: no-cache'  for the response didn't help.

Here is my SO post on the topic:

http://stackoverflow.com/questions/9930564/possible-to-disable-rack-cache-on-a-per-request-basis-in-rails-3-2

Is Rack-Cache incompatible with streaming responses??? 

Can anyone think of a way to disable Rack-Cache for this one request???

Thanks!
